I wondering if its necessary to format a new 1 or 2 TB hard drive, like WD or Samsung, if the drive already comes pre-formatted with NTFS file system. I'm plan to use the drive on a Windows 7 system.
My concern is sector errors which may have occurred during transit in the postal system. I mean how do I know if a new preformatted hard drive is good after I get it via postal mail delivery (USPS, UPS, FedEx, etc), if I don't format first, even if its already preformatted when I get it?
99% of the time no format is necessary when pre-formatted. So long as the Install button is not greyed out and it doesn't force you to after pressing it, everything is good. (It will not format without permission.)
